Aloha?

My daughter just asked me if I knew how to say "Hello" and "Goodbye" in Polynesian.

I told her yes, and that it was the same word. Next, I asked her if she knew that word.

She affirmed by saying, "Aloha."

Overall, this was a rather unimpressive exchange, other than it got me thinking how stupid that Beatles song "Hello Goodbye" must sound when translated into Polynesian.

Are there times when it says, "You say hello, and I say hello?" or "You say goodbye, and I say goodbye"?
